Like Mozart and Michael Jackson, Picasso was pumping out masterworks before puberty and demonstrated the key features of early bloomers: he was prolific, energetic, intuitive, idea-driven and speedy. At 15 and while still in art school, young Pablo painted his sister Lola in The First Communion — you can see it at the Museu Picasso in Barcelona with many of his other adolescent efforts. University of Chicago economist David Galenson, after analyzing auction results, concluded that Picasso’s earliest works are his priciest and therefore his best. According to Galenson, the poor guy peaked early.
